difficult cold start

[4strokeluvr111]

How's this idea for you starting fluid lovers.......drill a hole in your airbox at such an angle that the starting fluid nozzle will spray into the carbs. Once she fires, use a grommet to close up the hole. Using this type of setup when fogging/winterizing a couple of outboard motors I've had in the past.

i like it and at the same time i dont, if you had a backfire like he did and you were putting it through a small hole you would definitely blow that airbox up completely maybe even damage the engine, plus your not 100% sure its all making it into the throat, with enough practice and a small amount of fluid it would prob be ok but just gotta be careful. and plug the hole up after with a plug or something

my thoughts were adding an inline marine style fuel primer bulb. between the tank and the pump. this is exactly how a Yamaha marine carbed 4 stroke engine is set up. as for as a check valve, yes it has one inside, if it didn't you squeeze it and it would pump back into the tank. i see no reason this would not work. my sled is not near by but i will try this mod next weekend.

Hello fellow forum members....I'm new to this forum and decided to do a search after experiencing the same "no start" condition when I tried to fire up the sled this summer. It had been sitting for a couple of months in an enclosed trailer and no doubt the summer temps inside the trailer caused the fuel evaporation issue. I just purchased the sled late in the season this year (an 06 RS Venture with 2500 km on it) and I only had one ride on it before the snow was gone. I ended up disassembling the fuel pumps thinking that they had dried up. But with a little quick start, it fired up and ran fine. I really don't like using quick start on any engine so now that I've learned about blowing on the vent tube - all is good. Great information here for a new owner. Thanks!

What I do is pull the air filter cover & give each carb a shot of WD 40, works every time.

Blow in the gas tank vent line as described earlier, works very well.
